Season 6 of 'Dexter' jumped forward a year, with Lumen out of the picture and America's favorite serial killer of serial killers back in the swing of things. By back in the swing of things, we mean of course, back to swinging his blade against Miami's murderers and criminals.

In one of the opening scenes, Dexter traps two first responders who had been killing patients and shocks them to death, proving why TV doctors must always yell, "Clear!" before using a defibrillator. Later, at a high school reunion, he tracks a jock who killed his wife, and after some flag-football forensics, introduces him to his table, too.

The rest of the episode took us to Dexter's 20-year high school reunion and introduced a pair of creepy, religiously inspired serial killers. Read more about the premiere after the jump.
